Notice
Upon recompilation only the contour elements that were created with
free contour programming are regenerated. In addition, only the texts
that were added using the "Free text input" input field are recompiled.
Any changes you made directly in the program text are lost. However,
you can subsequently insert and edit user-defined texts, which will not
be lost.
Sequence of operations
The input screen for the contour start point is displayed.
The input field with the input focus is indicated by the yellow
background color. Once the input is acknowledged with "Accept
element" or "Abort", you can navigate around the contour chain using
the ↑ ↓ arrow keys. The current position in the chain is indicated in
red.
Select the "Accept element" softkey to store the starting point. You
can add the next element by selecting the appropriate softkey:
The approach motion to the starting point can be changed from G0
(rapid traverse) to G1 (linear interpolation) via the "Approach starting
point" field. You can define a specific feedrate for G1 via the "Free text input"
field,
e.g. G1 F0.3.
